Unity/C#：在垂直跳跃前检查速度？

Question

How do you convert rb.velocity into an integer?

I attempted to have if (rb.velocity < 0) to then make a jump be able to add to existing momentum without jumps doing nothing if the negative momentum is to high.

Answer 1

To make the comparison, you just need to do if (rb.velocity.y < 0) . This checks if the vertical velocity is less than 0, which is what you really want.

However, I would also recommend you instead set rb.velocity = 0 every time you jump before applying the jump force (or however you may be making the jump) for consistency.

Answer 2

In order to get the velocity to an int it's pretty easy

int speed;
//By grapping the total magnitude which is x*x+y*y+z*z we get total speed value
speed = (int)rb.velocity.magnitude;
